games about exploring twisted, confused structures

i want games that evoke the same feeling of exploring a closed, confusing space that i got playing ultrakill's fraud layer for the first time, or playing a super mario 64 mod called b3313, or playing doom's myhouse.wad

after playing fraud i REALLY want the feeling of being lost exploring some structure that don't make sense, BUT i need an important detail about all the stuff i mentioned above: every room has to have something interesting for you to do, and for you to feel like your making constant progress but also feels like you're making none

i think metroidvanias would be a great place to start, but idk if there's any metroidvania like that

also i value games that have great replayability, like having different builds and loot i can play with, but it's not a requirement
